Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...
Friedrich Hoffmann conducted the first modern scientific investigation into carbon monoxide poisoning from coal in 1716, notably rejecting villagers attributing death to demonic superstition. Herman Boerhaave conducted the first scientific experiments on the effect of carbon monoxide (coal fumes) on animals in the 1730s. [9]
For instance, in the compound K 2 O, potassium (K) is a metal and therefore its proper name is potassium oxide, rather than potassium monoxide. Among monoxides, carbon monoxide and dihydrogen monoxide are both neutral, germanium(II) oxide is distinctly acidic, and both tin(II) oxide and lead(II) oxide are amphoteric.
Carbon monoxide is a dangerous and silent killer. The colorless and odorless toxic gas kills hundreds of people every year and sickens thousands more, according to the U.S. Centers for Disease ...
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
If you believe you have been exposed to carbon monoxide or are at risk of CO poisoning, Bruccoleri says you can call the Tennessee Poison Center at 1-800-222-1222. The Center is staffed 24/7, 365 ...
